Owing to their chemical structure triazine herbicides can undergo N-ni
trosation. In this work the formation of N-nitroso derivatives of atra
zine, terbuthylazine, terbutryn, and terbumeton was evaluated. The kin
etics of formation is discussed in relation to the structural features
of the compounds and the ratio triazine/NO2- in amounts similar to th
ose present in human gastric juice.
